Abstract

The present invention provides methods for deinking printed waste paper - particularly methods that use a deinking composition that includes a hydrophobically-modified inorganic particle ('MIP') to improve ink collection efficiency under traditional alkaline, reduced alkali, and true neutral deinking conditions. Deinking compositions are provided that include a hydrophobically- MIP substrate, a nonionic surfactant, and a fatty acid, or mixtures thereof. The improved ink collection of the present invention can result in deinked pulp of high quality and/or yields that has excellent brightness and effective residual ink concentrations ('ERIC') values.
